Wordpress - Custom Fields and Meta Data

Identify the error in this code snippet:

echo get_post_meta('price', 15, true);

AFunction get_post_meta() does not exist

BMissing third parameter

CParameters are in wrong order

DPost ID must be a string

Step-by-Step Solution

Solution:

Step 1: Check parameter order in get_post_meta()
The correct order is get_post_meta($post_id, $key, $single). Here, 'price' (key) is first and 15 (post ID) second, which is wrong.
Step 2: Confirm other options are incorrect
The third parameter is present, the function exists, and post ID should be an integer, not string.
Final Answer:
Parameters are in wrong order -> Option C
Quick Check:
Post ID first, key second in get_post_meta() [OK]

Quick Trick: Post ID always comes before key in get_post_meta() [OK]
